Text Solution

AI Generated Solution

### Step-by-Step Solution: 1. **Understanding Avogadro's Number**: Avogadro's number, denoted as \( N_A \), is a fundamental constant in chemistry that represents the number of particles (atoms, molecules, ions, etc.) in one mole of a substance. 2. **Nature of Avogadro's Number**: Avogadro's number quantifies the amount of substance in terms of the number of constituent particles. It is defined as: \[ ...

    If 0.8 mole of electrons flow through a wire in 55 minutes. What is (a) the total charge in kilocoulomb that passes through the wire and (b) the magnitude of the current? Avogadro's number =6xx10^(23) per mole.

    Gold (Au) is a precious metal used mainly in jewelry. What is the mass in grams of one AU atoms ? Strategy : We expect that the mass of a single Au atoms in grams would be very small number. The atomic mass of Au is 197.97 u . Thus, its molar mass is 196.97g. Because each mode of a substance contains Avogadro's number of units of that substance contains. Avogadro's number of units of that substance dividing the mass of the substance in one mole (molar mas) by Avogadro's constant gives the mass of that unit of substnace.
